I'm not sure if I believe this...if that's true that they're still considered living, wouldn't that mean that unconscious non-infected humans would be safe from rats too?

I'm not sure that I understand. Why would non-infected humans not be attacked? The rats avoid the weepers because of their plague condition not the fact that they are alive.

Then why did the rats eat the unconscious Weeper bodies in the screenshots in galacticninja's answer?
